To all whom it may concern.-

Be it known that I JOHN C. CROMWELL, a citizen of the United tates, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful lm-' provement in Driving Mechanism, of which the following is a specification, the principle of the invention bem herein explained and the best mode in whic I have contemplated applyin that principle so as to distinguish it from 0t er inventions.

My invention relates to driving mechanism, and particularly to the latter as it is used in combination with the frames of centrifugal separators, and has for its object the provision of driving mechanism of this character which shall satisfactorily fulfil the general purposes forwhich said mechanism is intended and the parts of which, together with said frames, may be readily and easily assembled and dismantled.

Said invention consists of-mechanism hereinafter fully described, and specifically set forth in the claims.

The annexed drawin description set forth in etail certain mechanism embodyingthe invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Fi

of the frame of a centrifuge separator upon which is supported and within which is inclosed my improved driving mechanism, said section being taken upon t e plane indicated by the line 1 1, Fig. 2 and some connecting arts bein shown m elevation. Fig. 2 re re- 3 nts a si e elevation of the mechanism i us trated in Fig. 1, with arts shown in vertical transverse section, ta en upon the plane indicated by line 2 2, Fig. I. Fig. 3 represents a perspective view of one part of a twopart frame comprisi an element of my invention, which part 0 the frame is so arable from the remainder of the frame an within which all the gearing connecting the drivin and the following x re 1 repre sents a broken vertical ion ltu nal sectlon In general the features of a centrifugal separator are comprised in a frame, means mounted upon the same within which the constituent liquids are separated by centrifugal action, a driving-gear, and connections upon the frame between said driving-gear and said separating means and inten e to impart a rotation to the latter and secure the necessary centrifugal action. In the centrifugal se arators heretofore in use consider able time as been consumed and great difficulty encountered in assembling and dismantling the different parts of the frame and the caring inelosed by them,'which connects the rivingear and separati means.

It is the ohject of this invention to obviate these difficulties and save this time by providing driving mechanism and a frame part carrying this mechanism which shall be readily removable from the remainder of the frame and readily inserted in the same for assembling the whole mechanism for operation.

The essential features of my invention are comprised of a two-part separable frame, one

art A of which is shown in perspective in 3 and the other part of which is shown at C 1n Fig. 1, a driving mechanism carried by said part A and connecting the driving-gear, and the vertical shaft d, carrying the se arating'bowl D. Further, the general eatures of a centrifugal separator are provided as follows: A drivm -gear B is carried upon the shaft b, journals in suitable hearings in the-part C of the frame, which driving-gear is operated b a crank b. The separating means, inclu 1n the bowlD, is carried upon the vertical shalt d, suitably journaled in-an upper bearing d on the'part c of the frame w an in a lower bearing :2, located in the part A of the frame. The connections between the vertical shaft 5 and the driving pear B will be hereinafter full described. he retation of the shaft d is mtendecl to secure the rapid rotation of the bowl D and aconsequent separation of the constituent liquids. The 100 lower standards of the separator are not shown in the drawings.

' Passing centrally and transversely through the art A of the frame and suitably ournale therein by the bearings cand a is a to 5 worm-wheel an pinion sha t afand carried upon the latter within the part A of the frame is a worm-wheel E, meshing with a worm d upon the lower part of the vertical shaft (1.

A pinion F is'carried upon the shaft 0. and no meshes with the drivin ear B. Concentrio with the worm-whee and formed in a central recess e of the same and around the shaft (1 is a clutch G of such a size as to form between the flange e,bounding said recess e,

and the periphery of the clutch G a ballgroove g, within which are contained the alls g, the peri hery of said clutch G converging in severa places toward the flan e e, the-construction being. such that the ba ls g are permitted free play for a short distance in said ballroove g, as will be hereinafter more fully escribed. The hub e of the worm-wheel E is loose upon the shaft (1, while the hub of the clutch G is rotatably fixed to said shaft 11 by means of a suitable pin 9*, so that it will be noted the worm-wheel E can rotate freel upon the shaft a independent of the clutc G when the shaft (1 is rotating in the direction denoted by the arrow in Fig. 1, the balls g remaining in the enlar ed portions of the ball-groove 9 when the sha t a is rotating in said direction. However, if the shaft a is rotating in the other direction, the balls 9 will become wed ed in the con stricted portions of said he -groove 9 between the flange e and the eriphery of clutch G, so as to bind upon t e same and cause the worm-wheel E. and the clutch Gto rotate together. The art A of the frame is secured to the part 0 means of screws 0, Fig. 2, there being provided in the form of device shown one such screw at each corner of the rectangularly shaped back a of the frame art A. g

It will be noted from the above description that the frame carrying and inclosing the driving mechanism is composed of two parts, that t ey are readily separable one from the other, and that they jointly form an inclosing casin On carrie by the part 0 of the frame, the other bearing of the vertical shaft and the two bearings of the worm-wheel and pinion shaft 0, being carried by the part A of the frame.

As can be readil part A forms a'shiel for the worm-W eel and at its lower portion an oil-reservoir A. The part A of the frame and the gearing contained within the same form the sole intermediate connection'between the driving-gear B and the vertical shaft 12, which carries the separating-bowl D, and by simpl lifting up such bowl and carryin the shaft out of the lower bearing 11 and t on removing the screws 0 the part A and all the connectingearing with it can be separated from the rivin gear B and the part 0 of the frame, the mec anism being thus completely dismantled in a few moments time and by means of a' few sim le operations. a
